V p my invention, the numeral lde'signates general-1y In lieu of the axial coil spring employed in my 'cupied and Vacant.

prior patent for holding the lever 9 in its normal inoperative position, I provide in the present instance the leaf spring 31 and the manner in which this leaf spring co-operates withthe lever is clearly illustrated in Figure 3 of the drawing.

The spindle on which the outside knob 15 is secured is indicated at 16 and this spindle extends through the front wall and the cover plates 20 and 28 respectively, and carried by the inner end of this spindle 16 is the arm 17, the same carrying at its upper end, the laterally extending fingers ll and 22 that are disposed above and below the retractile bolt 21. This unit of the lock is of substantially the same construction as the.

unit disclosed in my prior patent and a leaf spring 32 co-operates with the movable arm 1'7 for holding the same in its normal position.

v The lowermost finger 22 constitutes a rest on which the deposited coin lies while the upper finger acts as an operating means for co-operation with the coin to efiect the retraction of the bolt when the knob 15 is operated.

As clearly described in my prior patent, when the parts are arranged as shown in Figure 3, the lock may be opened by actuating the knob 15 and, this will result in the leverl'l swinging in an inward direction so that the finger 41 will push the coin against the remote shoulder of the recess 25 so that the coin acts as a connecting means between the lever and the bolt whereby the bolt may be retracted.

Of course, when a coin is not deposited in the opening 27, the lock cannot be opened from the outside unless a proper key engages the projecting outer end of the spindle 19. The key engaging means may be in the form of a lug l3.

' One of the improvements over my prior patent comprises an indicator for association with the lock whereby to indicate when the compartment is occupied or vacant and to this end, there is provided within the upper portion of the casing 1, the horizontal sliding plate 33 operable between suitable guides arranged within the casing. On the front face of this plate 33, there is inscribed or otherwise arranged the words Oct A sight opening 5 is formed in the front wall of the casing to display either of the indicating words.

A pin 11 projects laterally from the rear wall of the plate 33 and is disposed within the path of movement of the pivoted lever 6 and this lever is in turn provided with a projection 7 at its pivoted end that is disposed within the path of movement of the coin resting in the recess 25. It is readily obvious that when the coin moves inwardly with the bolt, said coin will operate the projection 7 to swing the lever 6 in one direction and'this lever will co-operate with the pin 11 to effect the actuation of the plate 33 so that the word Occupied will be displayed to view through the opening.

When the door is opened from the inside, the lever 9 will actuate the pivoted trip 10 to release the projected indicator slide plate 33 and the spring 34 will retract the plate so that the word Vacant will be displayed through the opening 5." The trip or trigger 10 holds the slidable plate 33 in place when the latter is in in use position. The lobes formed on the trip or trigger 10 act as a balance to throw the. trigger end of the trip 10 into the notch'iormed in-the plate 33-when the indicator slide plate is pushed back to the in use position. This trip or trigger 10 is mounted insuch a manner as to be disposed in coacting relation with respect to the lever?) so that when counter weight 8 co-operates with the pivoted lever 6 for returning the same to its initial position thus resetting the parts of the indicating mechanism so that said indicating mechanism will be positively operated.

As also explained very clearly in my prior patent, when the inside knob is actuated, the bolt will be retracted without effecting the movement of the arm 17 and the fingers 21 and 22 so that the coin resting in the recess 25 will drop into the bottom of the casing and the coins may be removed from the casing in the manner as proposed in my prior patent. Access may also be had to the interior of the casing and to the working parts of the lock in a similar manner.

It willthus be seen from the foregoing description, that I have provided a coin controlled lock that will at all times be positive and .efficient in parts may be resorted to without departing from.

the spirit or" the invention and the scope of the appended claims. V

Having thus described the invention, what I claim'is: I
